Daniel 6:4

With respect to the envy felt by the nobles, we see this vice rampant in all ages, since the aspirants to any greatness can never bear the presence of virtue. For, being guilty of evil themselves, they are necessarily bitter against the virtue of others. Nor ought it to seem surprising that the Persians who sustained the greatest labors, and passed through numerous changes of fortune, should be unable to bear with an obscure and unknown person, not only associated with them, but appointed as their superior. Their envy, then, seems to have had some pretext, either real or imaginary. But it will always be deserving of condemnation, when we find men selfishly pursuing their own advantage without any regard for the public good. Whoever aspires to power and self-advancement, without regarding the welfare of others, must necessarily be avaricious and rapacious, cruel and perfidious, as well as forgetful of his duties. Since, then, the nobles of the realm envied Daniel, they betrayed their malice, for they had no regard for the public good, but desired to seize upon all things for their own interests. In this example we observe the natural consequence of envy. And we should diligently notice this, since nothing is more tempting than gliding down from one vice to a worse. The envious man loses all sense of justice while attempting every scheme for injuring his adversary. These nobles report Daniel to have been preferred to themselves unworthily. If they had been content with this abuse, it would have been, as I said, a vice and a sign of a perverse nature. But they go far beyond this, for they seek for an occasion of crime in Daniel. We see, then, how envy excites them to the commission of crime. Thus all the envious are perpetually on the watch, while they become spies of the fortunes of those whom they envy, to oppress them by every possible means. This is one point; but when they find no crime, they trample upon justice, without modesty and without humanity, and with cruelty and perfidy lay themselves out to crush an adversary. Daniel relates this of his rivals. He says, They immediately sought occasion against him, and did not find it Then he adds how unjustly and perfidiously they sought occasion against him. There is no doubt they knew Daniel to be a pious man and approved by God; hence, when they plot against his holy Prophet, they purposely wage war with God himself, while they are blinded with the perverse passion of envy. Whence, then, does it spring? Surely from ambition. Thus we see how pestilential a plague ambition is, from which envy springs up, and afterwards perfidy and cruelty!
